Complete and
reliable solar
circuit protection
Eaton’s Bussmann business has more than
100 years of proven technical innovation to
help make your operation more productive
while protecting your equipment.
Solar Photovoltaic (PV) systems have, over the last 50 years, evolved into a mature,
sustainable and adaptive technology. The installations and demand for PV systems
increase the need for effective electrical protection. PV systems, as with all electrical
power systems, must have appropriate overcurrent and overvoltage protection.
Eaton’s Bussmann business has worked closely with solar system manufacturers and
through coordinated research and development, has produced revolutionary new fuse
links which, combined with its combiner box, offer complete protection for PV systems.

Introduction
With the rising energy costs of fossil fuels and their impact on the environment, the
focus on renewable energy has gained strength, which has led to an increase in the size
of Photovoltaic (PV) installations from 1.4 GW in 2000 to 137 GW in 2013. This rapid
growth in PV installations has challenged system designers, manufacturers and standards
organizations due to the special demands associated with PV installation in terms
of current, voltage, and ambient temperature. These requirements have also been
considered in the development of international protection standards for PV installations,
which Eaton’s Bussmann business, the leading name in electrical protection, has used to
develop PV specific protection devices.

IEC 60269-6 gPV standard
Unlike typical grid connected AC systems, the available shortcircuit current within PV systems is limited and the
overcurrent protective devices need to operate effectively on
low levels of fault current. For this reason Eaton’s Bussmann
business has conducted extensive research and development
of fuse links that are specifically designed and tested to safely
protect PV systems with high DC voltages and low fault
currents.
The International Electrotechnical Commissions (IEC) recognise
the protection of PV systems is different to standard
electrical installations. This is reflected in IEC 60269-6 which
defines specific characteristics that a fuse link is required to meet
for protecting PV systems, utilisation class gPV. Eaton’s Bussmann
series range of string and branch PV fuse links has been
specifically designed to meet this standard. However, Eaton’s
Bussmann series PV fuse links exceed the requirements of IEC
60269-6 as they operate at 1.35 x In (1.35 times the nominal
current). They also meet the requirements of UL 2579 and are
thus suitable for protecting PV modules in reverse current
situations.
Whilst the standard does not recognise a specific symbol, the
combination of the symbols for fuse link and strings are often
used to indicate a fuse link is suitable for protecting strings in PV
systems, see Figure 1.

Photovoltaic module construction
•
A photovoltaic (PV) cell is usually between 4” and 6” square.
•
A number of individual cells are combined in a module (often called a panel).
•
A number of PV modules in series is referred to as a string.
•
A number of strings in parallel is referred to as an array.
Figure 2
Photovoltaic module output
The voltage output of a PV module is defined by the number of cells in series that form the
module.
The current output of a PV module is dependent on the area of a cell.
The most widely used solar modules are made with 4’’, 5’’ and 6’’ poly-crystalline silicon cells.
This type of module using 6’’ cells, can achieve approximately 8 Amps maximum power point
(MPP) current per module with a typical voltage output of around 30 Volts.
With thin film technology typical output is 2.5 Amps and 40 Volts.
The maximum power point current of the modules vary between manufacturers of equal solar cell
dimensions. When selecting the appropriate fuse links, the specified Short Circuit Current (Isc) and
reverse current characteristics specified by the manufacturers should be used.
The specifications provided by the module manufacturer should be consulted to confirm the output
currents and voltages of the modules under the range of conditions expected for the proposed
installation. These conditions are influenced by the ambient temperature, the incident angle of
sunlight and the amount of solar energy reaching the module. These are usually mentioned as
coefficients on the manufacturer’s specifications.
Manufacturers also suggest the maximum series fuse rating or a reverse current rating. Both of
these are based on modules surviving 1.35 time this rating for two hours.

Overview of string protection
Depending on the desired capacity of the Photovoltaic (PV) system, there may be
several PV strings connected in parallel to achieve higher currents and subsequently
more power.
PV systems that have three or more strings connected in parallel need to have each string protected.
Systems that have less than three strings will not generate enough current to damage the modules
in the event of a fault. Therefore they do not present a safety hazard, provided the conductor is sized
correctly, based on local codes and installations requirements.
Where three or more strings are connected in parallel, a fuse link in each string will protect the
cables and modules from overcurrent faults and help minimise any safety hazards. It will also isolate
the faulted string so that the rest of the PV system can continue to generate electricity.
It should be remembered that PV modules current output changes with the module temperature as
well as the amount of sun they are exposed to. The exposure is dependant on irradiance level, incline
as well as shading effect from trees, buildings or clouds. In operation, fuse links, as thermal devices,
are influenced by ambient temperature. The current capability of Eaton’s Bussmann series PV string
fuse link should be derated according to the curves below.

How to select fuse links for string protection
Whilst a full study of all the parameters is recommended, the following factors should be used:
1.56 for current and 1.2 for voltage when selecting the fuse link. These cover most variations due
to installation. The same method should be adopted for crystalline and thin film modules.If your PV
installation is subject to extremes of high altitude, high irradiance, or low temperature, please consult
Eaton’s Bussmann business technical team ([email protected]).

The fuse link’s ratings should be selected as follows:
t Voltage rating ≥ 1.20 x Voc x Ns
t Current rating ≥ 1.56 x Isc
tCheck the current carrying capability of the selected fuse, after
derating at the ambient temperature of the fuse, still satisfies the
above criteria
t Current rating ≤ Imod_max_OCPR
t Current rating ≤ Iz = string cable rating
Eaton’s Bussmann business recommends using fuse links in both positive and negative cables, each with
adequate voltage rating (as above)
OR
If Np ≤ 3 and the cable is rated at 1.56 x Isc
However Eaton’s Bussmann business
recommends fuse links protection in all PV
systems as unpredicted fault currents may
occur in the event of inverter failure or where
batteries are connected to the strings.
For PV installations with three or less parrallel
strings and string cables adequately sized,
fusing may be needed if local installation
regulations or codes require them
OR
If Np ≤ 3 and the cable is not rated at 1.56 x Isc
Select fuse link to protect cable:
t Fuse link current rating ≤ Iz = string cable rating
t Voltage rating ≥ 1.20 x Voc x Ns especially if a battery is connected

Overview of array protection
Depending on the desired capacity of the Photovoltaic (PV) system, there may be
several PV strings connected in parallel to achieve higher currents and subsequently
more power.
A fuse link on each array will protect the cables from fault current and help minimise any safety
hazards. It will also isolate the faulted array so that the rest of the PV system can continue to
generate electricity.
A fuse link positioned in the cable that carries the combined output of a number of strings should be
protected by array fuse links. If a number of arrays are subsequently combined then a further fuse
link should be incorporated.
It should be remembered that the characteristics of PV modules vary with module temperature as
well as irradiance level. In operation fuse links are influenced by ambient temperature.

Data-line SPDs
Today many medium and large size PV systems incorporate
a variety of communication systems to monitor system
performance or provide security and surveillance. These
communication systems also need to be adequately
protected from potentially damaging overvoltage surges.
Eaton’s range of data-line SPDs are specifically designed to
provide surge protection for 2-wire and 4-wire RS-485
interfaces, RJ45 communications and BNC for video
configurations.
Importantly, installing this range of SPDs within the system will
protect not only the electrical interface but also the wider
network and the equipment associated with it.
